PowerPriceHub helps US households estimate household electricity use and understand the numbers on an energy bill.
Start with a useful estimate
Enter an appliance’s wattage, how long you use it, and the rate from your electricity bill. Our calculator shows the estimated kilowatt-hours and cost for a day, 30 days, a year, or a period you choose.
How we make estimates
We show the inputs, units, and formula behind our calculator. Electricity rates vary, so our calculator asks for yours instead of presenting a single national price as current. Equipment may cycle on and off, and bills may include fixed charges and taxes. Treat results as planning estimates.
